Abstract
In a multiple-direction input device, when the operation body is tilted, a push portion having a substantially spherical shape at the bottom of a operation body pushes a resistor element and detects a tilting direction and a tilting angle of the operation body from a resistance at a pressing point. Thus, the input device may operate in multiple directions in entire directions of 360°. The device can detect the pressing point of the push portion pressing the resistor element in accordance with the tilting direction and the tilting angle. The multiple-direction input device using less number of parts is capable of continuously detecting the tilting directions and the tilting angles.

- FIG. 13 is a sectional view of the conventional multiple-direction input device.
Operation knob 2A at the upper part ofoperation button 2 made of insulating resin protrudes out ofcircular hole 1A at the top of upper case 1 made of insulating resin.Support portion 2B protrudes at the lower center of theoperation knob 2contacts support hole 3A provided in wiring board 3 having wiring patterns (not shown) formed on the top and bottom surfaces the board. Four push-button switches 4 are mounted at the front, rear, right, and left aroundsupport hole 3A as a center on the upper surface of the wiring board 3. Theoperation button 2 can be tilted forward, backward, rightward, and leftward with a fulcrum, i.e., supportportion 2B.Push portion 2C disposed at the lower periphery end of theoperation button 2 contacts the top surfaces ofrespective operation portions 4A of the four push-button switches 4. - The multiple-direction input device is, as shown in the plan view of FIG. 14, installed in the middle of an electronic apparatus including a display6, such as LCD, and push-
buttons 7. The push-button switches 4 are electrically connected with a controller, such asmicrocomputer 8. - For example, as shown in FIG. 15, the
operation button 2, upon being tilted to the left, has thepush portion 2C at the left periphery end of theoperation button 2 push theoperation shaft 4A of the push-button switch 4 at the left, thus making the push-button switch 4 conductive. Then, a signal showing the conductive is input to themicrocomputer 8, and themicrocomputer 8 distinguishes which one of the push-button switches 4 is conductive. Thus, themicrocomputer 8 detects the tilting direction of theoperation button 2, i.e., forward, backward, rightward or leftward, and selects from a menu shown on the display 6. - However, when the conventional multiple-direction input device is intended to detect the operations in more directions, the device needs more push-button switches, thus including more components. The device can detect only the tilting direction but can not detect the amount of tilt or the tilting angle.

- FIG. 1 is a sectional view of a multiple-direction input device according to exemplary embodiment 1 of the present invention. FIG. 2 is an exploded perspective view of the device.
Operation knob 13A at the upper part ofoperation body 13 made of insulating resin protrudes out of circular hole 11A at the top ofupper case 11 made of insulating resin.Push portion 13B having a substantially spherical shape is located at the bottom of theoperation body 13.Resistor elements 15 placed on wiring board 12 are arranged a space apart from each other under thepush portion 13B. Theresistor element 15 includestop board 15A disposed at the top that is a film of polyethylene phthalate or the like having flexibility,electrodes top board 15A,upper resistor layer 15D formed by dispersing carbon or the like in resin which is printed between theelectrode 15B and theelectrode 15C,bottom board 151 that is a film of polyethylene phthalate or the like having flexibility,electrodes board 151,lower resistor layer 15F made of the same material as theupper resistor layer 15D which is printed between theelectrode 15G and theelectrode 15H, andspacer 15E having an adhesive coat on its top and bottom surfaces. Thetop board 15A and thebottom board 151 are bonded to each other by thespacer 15E. Theupper resistor layer 15D and thelower resistor layer 15F face each other at a predetermined interval.Outer periphery portion 13D unitarily formed with theoperation knob 13A and thepush portion 13B via elasticthin portion 13C of theoperation body 13 is located on the wiring board 12 having patterns (not shown) formed on the top and bottom surfaces. A predetermined space is provided between thepush portion 13B and thetop board 15A of theresistor element 15. - The multiple-direction input device is, as shown in FIG. 14, installed in an electronic apparatus having the display6, such as LCD and push-
buttons 7. As shown in the block circuit diagram of the electronic apparatus shown in FIG. 3, theelectrodes resistor element 15 are connected to acontroller including microcomputer 21 or the like viaanalog switch 23 that is an integrated circuit of a transistor or the like. - A resistance between
electrode 15B andelectrode 15C facing each other and a resistance betweenelectrode 15G andelectrode 15H are about 10 kΩ. - The
microcomputer 21 is provided with interrupt-input terminal 31 for detecting the start of pushing operation of theoperation body 13, and A/D-input terminal 32 for reading an analog voltage to detect a pushed portion. Each terminal is commonly connected toanalog switch 24, andresistor 33 of about 2 MΩ is connected between the terminal and a power source. - An input operation of the multiple-direction input device of the electronic apparatus will be described.
- First, in case of no pushing operation of the
operation body 13, themicrocomputer 21 controls theanalog switch 23 to connect theelectrode 15C of theupper resistor layer 15D to a ground and to disconnect theelectrode 15B of theupper resistor layer 15D, theelectrodes lower resistor layer 15F. Themicrocomputer 21 also controls theanalog switch 24 to connect theelectrode 15H to the interrupt-input terminal 31 and to disconnect theelectrode 15C. - Then, as shown in the sectional view of FIG. 4, for example, when the
operation knob 13A is pushed with a finger or the like, the central portion of thepush portion 13B pushes thetop board 15A, thus having the central portion of theupper resistor layer 15D underneath thetop board 15A contact the central portion of thelower resistor layer 15F opposing to thelayer 15D. Thus, as shown in FIG. 3, a current flows from the power source to theelectrode 15C at the ground via theresistor 33. Then, the potential of theinput terminal 31 of themicrocomputer 21 is connected to a ground potential changed from a power source potential. Thereby, themicrocomputer 21 recognizes the start of pushing operation of theoperation body 13. - Subsequently, as shown in the sectional view of FIG. 5, when the upper part of the
operation knob 13A of theoperation body 13 is tilted to the left with the finger, theoperation body 13 pressed downward turns to the left on a pressing point at the center of thepush portion 13B as a fulcrum. Then the pressing point pressing theresistor layer 15 moves to the left from the center of thepush portion 13B. - As shown in the sectional view of FIG. 6, when the knob is further tilted to the left, the
operation body 13 turns further to the left on the pressing point of thepush portion 13B, and then, the pressing point pressing theresistor layer 15 moves further to the left. - Similarly to this, when the
operation body 13 is tilted to the right, forward, or backward, the pressing point pressing theresistor layer 15 of theoperation body 13 moves in accordance with the direction of tilt and the angle of turn. - That is, the
operation body 13 turns on thepush portion 13B having a substantially-spherical shape, and then, the pressing point pressing theresistor layer 15 moves in various directions of tilt and the angles of turn in rightward, leftward, forward, and backward. That is, theoperation body 13 presses a specific point of theresistor layer 15 in accordance with the direction of tilt and the angle of turn in entire directions of 360°. - When the
operation body 13 is tilted as described above, themicrocomputer 21 controls theanalog switch 23 to connect theelectrode 15B of theupper resistor layer 15D to the power source, and applies a current to theelectrode 15C at the ground from theelectrode 15B, and then reads the voltage of theelectrode 15C from the A/D-input terminal 32. As shown in the conceptual diagram of FIG. 7, from the read voltage Vy, themicrocomputer 21 recognizes that the position of a point P, i.e., the pressing point of thepush portion 13B is located on a straight line A between theelectrode 15B and theelectrode 15C. - Next, the
microcomputer 21 controls theanalog switch 23 to disconnect theelectrode 15B andelectrode 15C of theupper resistor layer 15D, to connect theelectrode 15G of thelower resistor layer 15F to the power source, and to connect theelectrode 15H to the ground. Thus, a current flows between the terminals ofelectrode 15G andelectrode 15H of thelower resistor layer 15F. Themicrocomputer 21 controls theanalog switch 24 to connect theelectrode 15H to the A/D-input terminal 32, and then reads a voltage Vx of theelectrode 15H from the A/D-input terminal 32. In this case, as shown in the conceptual diagram of FIG. 8, from the read voltage Vx, themicrocomputer 21 recognizes that the position of the point P is located on the straight line B between theelectrode 15G and theelectrode 15H. - From these results, the
microcomputer 21 judges that the pushing operation has been executed at the position of point P, the intersection of straight line A and straight line B. And, themicrocomputer 21 processes the data of the position of point P and recognizes the tilting direction and the tilting angle of theoperation body 13. - Such operation of the multiple-direction input device causes the menu shown on the
display 22 of the electronic apparatus to change in accordance with the operating direction or the displayed cursor and pointer to move. - Further, as the
operation body 13 tilted at a predetermined angle, a displayed cursor and pointer may moved slowly by themicrocomputer 21. And as theoperation body 13 tilted further more, the displayed cursor and pointer may move faster. That is, in the electronic apparatus, the moving speed of the displayed cursor and pointer can be changed according to the tilting angle of theoperation body 13. - Also, a predetermined space may be provided between the
push portion 13B at the bottom of theoperation body 13 and theresistor element 15 in order to execute pushing operation as well as tilting operation of theoperation body 13. Themicrocomputer 21 may recognize the start of operation of theoperation body 13 by reading the resistance at the time of pushing operation. - Further, besides the selection of a menu with the tilting operation, the electronic apparatus may finalize the selection when the operation body is pushed with a menu.
- In this multiple-direction input device, a controller is connected to the resistor element, and the tilting direction and angle of the operation body are detected from the resistance of the
resistor element 15. Thus, the electronic apparatus used easily and being capable of executing multi-directional operations and of detecting the directions, angles, and operational loads. - (Exemplary Embodiment 2)
- The same components as those in embodiment 1 are denoted by the same reference numerals, and their detailed description is omitted.
- FIG. 9 is a sectional view of a multiple-direction input device in
exemplary embodiment 2 of the present invention.Operation body 53 includes a push portion having a substantially spherical shape formed at the bottom of the body. The portion is elastic like an elastomer. That is, this arrangement corresponds to the device of embodiment 1 in that thepush portion 13B at the bottom ofoperation body 13 is elastic. - FIG. 10 is a block circuit diagram of an electronic apparatus including the multiple-direction input device.
Resistor 63 is disposed between theelectrode 15B ofupper resistor layer 15D and the power source, and has a resistance of about 1 kΩ. A/D-input terminal 64 reads the analog voltage of theelectrode 15B. Other than the above are identical to embodiment 1. - When the
operation knob 53A is pushed with a finger or the like, as shown in the sectional view of FIG. 11, the central portion of thepush portion 53B pushes thetop board 15A, thus causing the central portion of theupper resistor layer 15D underneath thetop board 15A to contact the central portion of thelower resistor layer 15F opposing to thelayer 15D. Thus, similarly to embodiment 1,microcomputer 51 recognizes the start of pushing operation of theoperation body 53, applies a current to theelectrode 15C at the ground from theelectrode 15B, and reads the voltage ofelectrode 15C from the A/D-input terminal 32. - Further, in case the
operation body 53 is pushed at a higher strength, the contact area between theoperation body 53 and thetop board 15A increase since thepush portion 53B is elastic. Accordingly, since the resistance determined with theupper resistor layer 15D andlower resistor layer 15F decreases, the current flowing in theresistor 63 increases, thus causing the A/D-input terminal 64 to receive a decreased voltage. Themicrocomputer 51 recognizes a change of the voltage of A/D-input terminal 64 and detects an operation load to theoperation body 53. - The detecting the operation load to the
operation body 53 enables, for example, a map displayed on the display of an electronic apparatus including the multiple-direction input device to be enlarged and reduced in size with themicrocomputer 51 according to the change in the voltage of the A/D-input terminal 64. - In the above description, in the
resistor element 15, thetop board 15 A having electrodes upper resistor layer 15D is opposing to the bottom board15 I having electrodes lower resistor layer 15F. As shown in the exploded perspective view of an essential portion of FIG. 12, it is also possible to execute the present invention even in case theresistor element 15 includes fourelectrodes resistor layer 40D formed on the upper surface of the bottom board 40I, respectively. Theconductive layer 40F on the underside of thetop board 40A is opposed to theelement 15. - In this case, an operation of the
operation body 53 causes theconductive layer 40F on the underside of thetop board 40A to contact theresistor layer 40D on the upper surface of the bottom board 40I. The pressing point of the push portion can be detected from the relationship between the resistance across theelectrodes electrodes - According to the invention as described above, a multiple-direction input device is provided using less number of parts and capable of detection in multiple tilting directions and at multiple tilting angles, and an electronic apparatus including the device.
